IMPORTANT: If using PCI cards on shared slots, make sure that the drivers support “Share IRQ” or that the cards do not need IRQ assignments. Conflicts will arise between the two PCI groups that will make the system unstable or cards inoperable.

3.7.3 Communication and Networking Riser (CNR) Slot

This connector supports specially designed network, audio, or modem riser cards. Main processing is done through software and controlled by the motherboard’s system chipset. This provides upgradeable network, audio, and/or modem solutions at an incredibly low cost.

NOTE: CNRs are not included with this motherboard.
